Power Supply

A guitar pedal power supply provides clean, stable electricity to effects pedals, replacing individual batteries and reducing noise caused by inconsistent or shared power sources. Unlike simple daisy-chain adapters, dedicated pedal power supplies are designed to deliver the correct voltage and current each pedal requires while minimizing hum, ground loops, and signal interference. A reliable power supply is a foundational component of any pedalboard, especially as setups grow in size and complexity.

Most pedal power supplies feature multiple isolated outputs, commonly offering 9V, 12V, and 18V options to accommodate different pedals. Isolated outputs prevent pedals from sharing a common ground, which helps eliminate noise and ensures consistent performance. Higher-quality power supplies also provide sufficient current for digital pedals, multi-effects units, and time-based effects, which often draw significantly more power than analog pedals.

Guitarists benefit from a dedicated power supply in both live and studio environments, where reliability and low noise are critical. A good power supply simplifies setup, improves tone clarity, and protects pedals from power-related issues. For players building a dependable and quiet pedalboard, choosing the right power supply is just as important as selecting the pedals themselves.
